To all whom it may Be it known that L SAMUELCRAIQ'aciti zen .of theUnited States 'of America, .re-

siding at Decatur, in the county of Macon and State of ll linois,'haveinvented new and a ing a lifting medium underneath the two s of thevehicle for raising the wheels off the ground, said truck then beingmovable to carry the vehicle to any required 1 7 place.

Another object of the invention is to provide a wheeled truck havinglifting jacks secured thereto and means for adjust1 the truck so thatthe jacks will be dispose immediately under the axles of a motor vehiclein order that the same may be lifted and conveyed to any required placeor during repairs.

These, and other objects may be attained by means ofthe constructionillustrated in the accompanying drawings, in which,

Figure l is a side elevation andpartial section of a truck made inaccordance with my invention, portions being shown broken away to betterillustrate the construction. Fig. 2 is an end view of the truck. Fig. 3is a view in elevation of one of the lifting jacks, one of the membersof the casing for covering said jacks being removed to lllustrate theintenor construction. Fig. 4 is a top plan view of the truck. Fig. 5 isadetail sectional view of the lower end of the ratchet lever foroperating the. lifting bar of the jack. 6 1s a detail sectional viewillustrating the manner of mounting the caster wheels under the truck.

Referring to the drawing, the numeral 1 designates one section of arectangular adjustable frame, and 2 is the other section of the same,said frame being preferably made of strong sheet iron or steel, and thesection 2 being adjustable relatively to the section 1 by means of slots3 and bolts 4. The rectangular frame is mounted upon casters 5, one ateach corner of the frame, said casters comprising a pair of wheels 6journaledupon an axle 7 mounted in a yoke 8 having a central bearingmember 9 between the wheels 6. The yoke 8 is pivoted at 10 to a l stubshaft lhthe upper end of which is in a late '12isecured underneath theframe-r1, 2 means-of bolts-13." 'By this means'thezcaster wheds mayrotate upon the'axisi'll {and also upontheaxle-T.

j Mounted upon" each end of the truck 'fI'ameiSa-Iiftin elementcomprising acasing'cmnposedo two members-14, 15. Asthese liftingelements are substantially-idem tical at the opposite ends of the truck,the

descri 'tion of onewill serve 'as a'description of hot The two members14,15 of the easing are provided with fiangesconnected by the bolts 13to the truck frame, and within said casing is a rack bar 16 providedwith teeth 17 upon one side thereof. A pinion 18 mounted upon' thesquared shaft 19. journaled in the casing mesheswith the teeth 17 Therack bar 16 extends down through the casing and is held in mesh with thepinion 18 by means of a friction idler wheel 20 which bears against theedge of the rack bar opposite the teeth 17, as shown more particularlyin Fig. 3. A pawl 21 pivoted at 22 within the casing engages the teeth17 of the rack bar, and connected to the pawl 21' is a link'23, saidlink being connected to a foot lever 24 pivoted at 25 within the casingand extending through said casing and provided witha roughened footpedal 26. A spring 27 connects the foot lever 24 with the casing andholds the pawl 21 up to the teeth 17. In order' to release the awl 21, afoot placed upon the pedal- 26will withdraw the pawl from the teeth andpermit the rack bar 16 to descend. The casing 14, 15 is sustained bydiagonalbraces 28.

To operate the liftin wrench 29 is provided aving a bifurcated end 30 inwhich-is journaled a ratchet wheel 31, said ratchet' wheel having asquared bars 16 a ratchet aperture 32 extending therethrough to re- 1ceive the squared projecting end of the shaft .the truck. The operationof my invention may be briefly described as follows The lifting bars 16are adjusted to the required distances apart by means of the bolts 4 andslots 3 to occupy positions immediately under the axles of the vehicleto be lifted.

The levers 29 are then applied to the squared ends of the shafts 19 .toraise the vehicle from the floor, after which the truck is pushed to anyrequired place for repairs or for storing. By putting the foot upon thepedal 26 the lifting bar 16 descends, and the motor vehicle is againlowered to rest upon its tiresin an obvious manner.

From the foregoing, it will be obvious that a truck made in accordancewith my invention can be readily adjusted to lift a motor carriagewithout the slightest injury to any of the parts and without strainingthe mechanism; that the truck can be readily pushed under the vehicleand can be easily removed therefrom, able and eflicient.

, I claim In a device of the character described, a rectangular frame,

lever connected to said the operation being quick, reli caster wheelspivotally mounted in pairs in yokes underneath said frame, means foradjusting said frame longitudinally, lifting elements on said frame,each of said elements, consisting of a casing, a rack bar mounted tomove through the casing, a pinion meshing with the rack bar, a frictionWheel for holding the rack bar in mesh with the pinion, a pawl, a footpawl, a spring for holding said foot lever in position to keep the'pawlengaged with the rack bar, and a removable ratchet lever for rotatingthe pinion. y

In testimony whereof I afiix my signature in presence of two witnesses.

SAMUEL CRAIG.
